摘　　要：SDN为网络的集中管理灵活提供极大的便利,各种网络功能可以灵活动态地通过控制器部署到网络中,但这也带来了流表规则冲突的问题。通过对这个问题的研究,总结出规则匹配域的四种关系以及可能产生的四种冲突异常,最后分析得出应对方法,并理论上分析方法的正确性与可行性。SDN provides great convenience for the centralized management of network.Various network functions can be flexibly and dynamically de⁃ployed to the network through the controller,but this also brings the problem of flow table rule conflict.Summarizes the four kinds of rela⁃tion between the matching fields of flow rules and the resulting four possible conflict exceptions.Finally,we come up with a solution whose correctness and feasibility was theoretically analyzed.
